What is disclosed is a method and apparatus for writing servo information on disks to be used in a hard disk drive assembly. In one embodiment, servo information is pre-written onto a disk using an offline servo track writer which employs a fluid dynamic bearing spindle to rotate the disk(s) during read/write operations. In another embodiment, servo information is written onto a disk by a method of track following on a reference disk using an offline servo track writer.

Aerodynamic forces contribute to disk and actuator vibration leading to track positioning errors in storage devices such as hard disk drives. The invention provides a variety of dampening mechanisms and a method of dampening to alleviate these problems in single disk storage devices. This includes disk drives of at most 13 millimeters in height.
